The back plate 34, which joins the channel irons19 has an extension 35 which is 'provided with holes 36 through which the fingers 38 of the latch bar 37 project. The bar 37 carries a member 39 which is bent over at 40 andprojects down'at 41 between the pair of channel irons 19 so as to be susceptible of engagement by the angled iron 42 that is fastened beneath the rear axle 43 of the carriage orbucket 46. The axles 43 are mounted on the carriage or bucket 46 by saddle members and eachaxle43 carries a pair of rollers or wheels 44 to ride in the channel irons 5 and 19. The cables 48 are connected at 47 with the carriage or bucket V by any suitable mechanism (not shown), V y

In operation, the bucket or carriage: 46 may be initially positioned as shown in Fig. 1, at which time both trackage sections will have their respective channel irons 5 and19 held in alinement with each other and latched by virtue of the fingers 38, projecting through the hole's'36 and behind the angled irons' 7, which angled irons 7 also serve'as stops to be engaged by thechannel irons 19 when the parts are'in the position shown in Fig. 1. Now as tension is applied to the cables 48 to pull the carriage or bucket 46 upwardly,the wheels 44 pass fromthe channel irons 5 into the channel irons 19,

' and as the angled iron 42 on the rear axle fingers 38 from in back of the angled iron 7 43 engages the latch lifter 41, it will cause the latch 37 to be raised to withdraw the to unlatch the two trackage sections. At

this time also, the front wheels 44 of the carriage will have engaged the stops 24, thus further movement of the cables 48 in the di rection of the arrow in Fig. 3 "will cause the carriage or bucket 46, and, the trackage section 18, to move together as a unit, the rollers 26 following the groove 27 and-turning through an arc, having as its radius the central point 49 oftl e arc-section 28, while the lower or rear end of the movable track section 18 will move on an archaving as its centerithe pivot '10 and as its radius the length of the arms 22. Thus a continuous pull on the cables 48 serves to elevate the carriage 46and1 at the same time cause it to turn over to itsdumping position shown in Fig. 2 of the drawings. I 1

operation and advantages of the invention I Numerous changes in the details of conmadeto adapt therinven'tion to the particular use to which it is put and I wish-wit understood thatI do not'desire to limitmyself to the specific construction hereinshown v struction' and designing of parts may be and described, which specific construction is merely an-illustrative embodimentof the in vention.--

"VVhat'I claim is: a 1. A support, a traveling bucket or carriage a relatively fixed trackage section mounted on said support, said carriage having r011- ers to engage said trackagesection, a rela-f tively movable trackage section cooperating with said fixed trackage section and forming an extension thereof-,a link connection between one end of saidrmovable trackage sectlon and said support, segmental arc guide members mounted on said support,

sliding connections between said segmental arc guide members and the other end .of said movable trackage section, relatively fixed fulcrum members on which said mov: able trackage section bears, stops on. said movable trackage section for engagementzby the forward carriage rollers whereby said movabletraokage section and saidcarriage are moved together as'a unit to: effect the dumping of the I carriage substantially as shown and described. 7 5

2. A support including a pair of upright members, segmental arc guides mounted on said upright members and having grooves, rollers mounted on said segmental. are guides, a relatively fixed trackage section mounted .on said support, a relatively,.mov

able trackage section cooperatingjwith said fixed trackage section, 'rollersi mounted on one end of said movable trackage sectionto ride in the grooves of said se mental are members, said movable trackage. section' vadapted to ride on said segmental arc member rollers, and a carriage adapted toride on saidtrackage sections, and means for.

connecting said carriage and said movable trackage section together to cause themfto move as 'a unit when saidicarriage is on said movable trackage section, and means, for imparting movementto saidcarriage to elevate anddump the same. Y

3. A support includinga pair ofupright members, segmentalrarc guides mounted-on said upright members and having grooves, rollers mounted on said segmental are guides, a relatively fixed trackage section mounted on said support, a relatively movable trackage section cooperating With said fixed trackage section, rollers mounted on one end of said movable trackage section to ride in the grooves of said segmental arc members, said movable trackage section adapted to ride on said segmental arc member rollers, and a carriage adapted to ride on said trackage sections, and means for connecting said carriage and said movable trackage section together to cause them to move as a unit When said carriage is on said movable trackage section, and means for imparting movement to said carriage to elevate and dump the same, link connections between said support and said movable trackage section, and stops carried by said link connections for limiting themovement of said movable trackage section.

4. A support including a pair of upright members, segmental are guides mounted on said upright members and having grooves,

rollers mounted on said segmental are guides, a relatively fixed trackage section mounted on said support, a relatively movable trackage section cooperating With said fixed trackage section, rollers mounted on one end of said movable trackage section to ride in the grooves of said segmental are members, said movable trackage section adapted to ride on said segmental arc member rollers, and a carriage adapted to ride on said trackage sections, and means for connecting said carriage and said movable trackage section together to move as a unit When said carriage is on said movable trackage section, and means for imparting movement to said carriage to elevate and dump the same, and means for holding said fixed and movable trackage sections in alinement when said fixed and movable trackage sections are in contact and While the carriage is on the fixed trackage section.
